Compound, curable resin composition, cured product, optical member, and lens

Abstract

Provided are the following compound represented by General Formula (A) or (B), a curable resin composition including the compound, a cured product thereof, an optical member, and a lens: A ring Ar 1 and a ring Ar 2 represent an aromatic ring represented by a specific formula or a fused ring thereof, R 1 and R 2 represent a specific substituent, and v and w are a specific integer. R 3 and R 4 represent a hydrogen atom or a monovalent substituent, L 1 and L 2 represent an alkylene group having 1 to 6 carbon atoms, and Sp a to Sp d represent a single bond or a divalent linking group. Pol 1 and Pol 2 represent a hydrogen atom or a polymerizable group, in which at least one of Pol 1 or Pol 2 is a polymerizable group. Further, in the formulae, a structure represented by (R 1 ) v —Ar 1 /cyclopentadiene skeleton/Ar 2 —(R 2 ) w is not line-symmetrical.
